The 107PHQ is a transportable APO refractor for astrophotography with corrected field of view up to full frame sensor and for observation up to the highest magnification range.
This long focal ratio flatfield apochromat support 60 mm image circle and does not need calculations for backfocus. If the image is sharp, the field is flat.
130 mm aperture, 1000 mm focal length, f/7.7
Petzval like, self flattening design with two ED elements
3.4" dual speed focuser
2" and 1.25" receptacles, M68, M54 and M48 threads
With the FMA180 Askar has created a triplet APO refractor with unique visual and photographic applications
With just a few simple steps, the APO telephoto lens can be transformed into a compact astronomical telescope, a guide scope or a powerful spotting scope for landscape observation.
Aperture 40 mm
Air-spaced triplet ED lens for almost pure color image
Photographic focal length 180 mm (with corrector) - focal ratio f/4.5
2" filter thread in front of the objective for nebula filters
Focal length for observation 220 mm
The photographic field of view is up to full frame size
Precise helical focuser on the lens for accurate focusing - with locking mechanism T2 camera connection with 55 mm working distance (when used as telephoto lens)
Weight only 395 grams
Can easily be attached to the telescope instead of the finder
Fits on any ball head - also ideal for mobile astrophotography with photo trackers like the Sywatcher Adventurer
Ideally suitable also as mini guide telescope
The FMA180 can be converted into a compact spotting scope for observation in just a few steps
